JRS4 Contactor

The JRS4 series thermal overload relay (hereinafter referred to as thermal relay) is mainly used in AC 50Hz/60Hz circuits with a rated operating voltage of 690V and below, and a current of 0.1A to 80A, for overload and phase loss protection of three-phase AC motors. The thermal relay features phase loss protection, temperature compensation, operation indication, manual reset, and stop functions (manual reset and stop functions are achieved via the same button). This product operates reliably. The thermal relay can be plugged into a contactor or installed independently.
Compliant with standards: GB/T 14048.4, IEC 60947-4-1, etc.
For combined installation, the corresponding thermal relay models are JRS1-09~25, JRS1-09-25X, JRS1-40~80, and JRS1-40~80X. For independent (screw) installation, the corresponding thermal relay model is JRS1-40~80/F.
Rated operating voltage: 0.1~80A
Trip rating: 10A
Rated insulation voltage: 690V
